SWDEV-78467 - Adding 'CL_FILE_SIZE_AMD' queriable property for file objects.
	While validating the LF extension we noticed a common use case in which the programmer has to query the size of the file being processed.
	This enhancement will save the programming overhead of opening and closing files using some other API just in order to query their size.

	This feature is being integrated from LF dev branch 15.30.1023.
